Last week she sparked pregnancy rumours after flashing her tum while out and about in Los Angeles, and now Jessica Biel has been congratulated on her "impending motherhood" by a US magazine editor.

According to Us Weekly, Ariel Foxmon, Editor-in-Chief of InStyle, shared a shot of of the two of them together at the premiere of Total Recall in 2012 under the caption: "Congrats @jessicabiel on your impending motherhood.

The 32-year-old looked relaxed as she aimed to cover up in a scarf and jeans, but she didn't think the shirt through.

Fans on Twitter quickly expressed their excitement, with one writing: "Jessica Biel fans aren't mad about anything. She's pregnant and Justin's still happily married to her. WE CELEBRATING."

Another added: "Is Jessica Biel pregnant?"

We know they are considering starting a family together, because the brunette beauty told E! last year she tapped into the mind of a mother, as she filmed scenes for The Truth About Emanuel.

She said: "I think to make this person, this character, work without being some ridiculous, crazy performance, is to really believe in what she's doing and believe that that is her truth, that baby is her baby and that's what it is.

"And so the nurturing element of being a mother, that is really what I tapped into. Because it's like, the best villain really believes what they're doing. It's the same idea. This woman, that's just her truth, her reality."

And when asked if she'd consider it with Justin, she added: "I don't know. I'm not quite sure about sooner or later, but definitely at some point."
